Webb1 okt. 2001 · This allowed for comparison of behaviors in freshwater and in saltwater in the same group of animals. Behaviors related to thermoregulation (basking and staying in the water) and feeding were recorded via instantaneous sampling, in which sampling intervals of 1 min occurred throughout a 20 min observation period. Webb20 juni 2011 · Conversely, nonmigrants must cope with a wider range of T a s and availabilities of energy, and should therefore be less sensitive to changes in T b. If thermoregulation and thermal sensitivity are co-adapted, we would therefore expect migrants to be relatively less heterothermic compared to closely related nonmigratory …

According to a study at Harvard University, our bodies have two main ways of regulating temperature, including behavioral and physiological mechanisms.

By numerous observations upon humans and other animals, John Hunter showed that the essential difference between the so-called warm-blooded and cold-blooded animals lies in observed constancy of the temperature of the former, and the observed variability of the temperature of the latter. Almost all birds and mammals have a high temperature almost constant and independent of that o…
